The name of the Chesters Roman fort is first mentioned in the "Notitia Dignitatum' of the late-4th/early-5th century, wherein it is listed as 'Cilurnum'.

'Cilurnum' or 'Cilurvum' was a Roman fort on Hadrian’s Wall at Chesters and marks the point where the Wall crossed the River North Tyne, the first major obstacle on its route from east to west. River North Tyne is a river in North East England. Its length (excluding tributaries) is 73 miles (118 km)

Chesters is one of a series of permanent forts built during the construction of Hadrian’s Wall. The cavalry fort, known to the Romans as Cilurnum, was built in about AD 124. It housed some 500 cavalrymen and was occupied until the Romans left Britain in the 5th century.
